What is a “gang box”?

A “gang box” is defined as a box designed to hold multiple devices, which is why the second choice is the correct answer. These boxes are commonly used in electrical installations to accommodate more than one switch, outlet, or other devices in a single location, allowing for more efficient use of space and enhancing the functionality of the electrical system.

Gang boxes come in various sizes, allowing for two or more devices to be installed side by side, enabling better organization of electrical components in residential and commercial settings. They ensure that all devices are securely housed and provide the necessary room for wiring, which supports safe electrical work.

The other options describe characteristics that do not define a gang box. While it might be possible to mount a gang box on a wall, that alone does not make it specific to what a gang box is. Similarly, restricting the design to outdoor use, or indicating that it can hold only a single device, diverges from the true purpose and usage of gang boxes in electrical installations.
